JOINTED BEAM FOR CULTHVATORS.

SPECIFICATION forming part of LettersPatent No. 745,478, dated December1, 1903.

Application filed July 20,1903. $erial1lo. 166,408- (No model.)

els attached to the beams in one furrow in place of making threedistinct furrows in parallel line with each other and a row of plants,and also to throw loose ground upon plants to cover them up when thebeam inclines toward the row of plants to which ground is to be moved.

My object is to retain the shovels in position while in operation asrequiredto make three distinct equidistant parallel furrows in parallelline with a row of plants as a cultivator is advanced in parallel linewith a row of plants; and my invention consists in the construction andcombination of a jointed beam with a hinge adapted to be fixed to acarriageaxle or cultivator frame; as hereinafter set forth,pointedoutinmy claims,and illustrated in the accompanying drawing, that is a planview in full lines and dotted lines when deheated to the right or left.

The numeral 10 designates a beam, and 12, 13, and 14: cultivator-shovelsfixed to the beam in such a manner that when the beam is advancedparallel with a straight line each shovel will make a distinct furrow,and the furrows will be in parallel position with each.

'motions to the beam 10 and cross-head 15 and said links, as indicatedby full and dotted lines.

A leaf-hinge 19 is fixed to the front of the part 16 in such a mannerthat the complete device can be hinged to the axle of acultivatorcarriage or carriage-frame as required to allow verticalmotion only to the piece 16, while at the same time the links 17 and 18and the beam 10 can vibrate to the right or left freely when the horsesdeflect from a straight line or when the cultivator is advanced on theside of a hill.

Standards a, b, and c are fixed to the beam 10 to operate shovelsattached thereto as required to produce three equidistant furrows at alltimes parallel with each other, with the line of advance, and alsoparallel with the row of plants cultivated thereby.

Having thus described the purpose of my invention, its construction, andoperation,the utility thereof will be readily understood by personsfamiliar with the art to which it pert'ains, and 7 What I claim as new,and desire to secure by Letters Patent, is'

1. A cultivator-beam having a cross-head at its front end extendinghorizontally anda corresponding cross-piece pivotally connected withsaid cross-head by means of two parallel links in a horizontal plane andmeans for hinging the pivoted cross-piece to a cultivator-carriage, forthe purposes stated.

2. A cultivator-beam, standards carrying shovels, a cross-head fixed tothe front end of the beam to extend horizontally,a correspond ingcross-piece, two parallel links in a horizontal plane pivotallyconnected with the fixed cross-head and the corresponding cross-pieceand a hinge fixed to the said pivoted crosspiece; arranged and combinedto operate in the manner set forth for the purposes stated.
